[gentoo-amd64] 2.6.22 and the rt2500/rt2x00 wireless drivers

[Vladimir G. Ivanovic]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Kernels before 2.6.22 could be configured with "CONFIG_NET_RADIO=y"
which would allow the rt2500 legacy driver for the Ralink wireless
chipset to compile. I've had this combination working now for over a year.

Starting with kernel 2.6.22, NET_RADIO is apparently no longer a
configuration parameter, so I can't compile the rt2500 legacy driver,
nor can I compile the newer rt2x00 driver which also depends on NET_RADIO.

Has anyone gotten a rt2500/rtx00 driver to compile with 2.6.22? What
patches are needed? Is there a HOWTO somewhere? (The Gentoo Wiki
articles "rt2500 on AMD64" and "rt2x00" don't seem to address my
issue. In any case, neither the latest CVS of rt2500 (2007051606) nor
the latest ebuild (net-wireless/rt2500-1.1.0_pre2007020911) compile
with KERNDIR=/usr/src/linux-.6.22-gentoo-r1. The latest ebuild
compiled just fine with kernels before 2.6.22.)

Any help would be appreciated. Thanks.

Just guessing: Maybe your problem has something to do with the newly 
introduced WLAN stack starting with 2.6.22 ...

Hi,

the rt2x00 ebuild in portage is out-dated.

The rt2x00 project has migrated to git for quite a while. They now
provide nightly tarballs for the part related to the rt2x00 modules
(without which you have to import the entire git tree to build the drivers).

I've made an ebuild using this nightly tarball. You can find it attached.

I've been using it for over a week and it works.

I guess gentoo wireless guys are updating the official ebuild the same way.

With the ebuild attached it's better ;-)

You can dig bugzilla and find two entries too :

http://bugs.gentoo.org/show_bug.cgi?id=176148
	=> an ebuild from the git repository by Jakub Moc (you can trust
	 him ;-))

http://bugs.gentoo.org/show_bug.cgi?id=185229
	=> an ebuild similar to mine

Now you have three choices :-)

Actually this one seems outdated too because it depends on some ebuilds
building modules that have been merged into 2.6.22.

Jakub please correct me if I'm wrong.

Thanks. I'll give your ebuild a try first, and then (if needed) the
last one you suggest below.

Thanks.

Notive the rt2500 ebuild in portage has been bumped and the changelog 
indicates it now works on kernel >= 2.6.22 :

*rt2500-1.1.0_pre2007071515 (15 Jul 2007)

  15 Jul 2007; Roy Marples <uberlord@gentoo.org>
  +rt2500-1.1.0_pre2007071515.ebuild:
  New CVS snapshot, fixes #181973.
  Added kernel tests for >=2.6.22, #181984 thanks to Ed Catmur.
